    Abstract: The invention relates to relief plates for flexographic printing comprising a relatively soft elastomeric base (U) having a modulus of elasticity of from 10 to 200 kg/cm2 and a thickness of from 0.5 to 6 mm and, firmly bonded thereto, a thin, relatively hard, difficultly soluble intermediate layer Z having a modulus of elasticity of from 1 x 103 to 2.1 x 106 kg/cm2 and a thickness of from 5 to 500 mu and, firmly bonded to said intermediate layer Z, a relief layer P' consisting of a photocrosslinked elastomeric mixture having a modulus of elasticity of from 30 to 2000 kg/cm2 and a thickness of from 200 to 300 mu , the modulus of elasticity of the photocrosslinked relief layer P' being the same as or higher than that of the base U and the neutral surface of the relief plate lying in or near the intermediate layer Z. The invention also relates to photosensitive laminates for the production of such plates.

    Abstract: Herbicides based on an aqueous suspension of from 20 to 50 percent by weight of 1-phenyl-4-amino-5-chloro-pyridaz-6-one or 1-phenyl-4-amino-5-bromo-pyridaz-6-one, from 2 to 10 percent by weight of dispersant, from 0.5 to 5 percent by weight of silica and from 0.5 to 5 percent by weight of a block polymer of propylene glycol, propylene oxide and ethylene oxide, which additionally contain a thiolcarbamate, a chloroacetanilide or a 2,6-dinitroaniline, the weight ratio of pyridazone to thiolcarbamate, chloroacetanilide or 2,6-dinitroaniline being from 4:1 to 1:2, a process for their preparation, and their use for combating undesired plant growth.
